NONSKIDDING AUTOMOBILE WHEEL.

Application filed March 26, 1928. Serial 1\To.'2 64,828. i

This invention relates to a new and useful 7 device in the nature of a non-skid automobile wheel especially adapted for the purpose of providing traction on ice, trozen snow or the like or on rough roads, and as a means of preventing skidding ot' the automobile equipped with my improved wheel.

The object of the invention is to provide a non-skid automobile wheel of novel construction and arrangement of parts hereinafter more fully described, claimed, and illustrated in the accompanying drawing.

Fig. 1 is a front elevational view of my improved non-skid automobile wheel. g Fig. 2 is an edge elevational view thereof.

Fig. 3 is an enlarged transverse sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is a similarsectional view taken on the line 4-4 of Fig. 1. V v

Fig. 5 is a similar sectional view taken on the line 55 of Fig. 1.

Fig. 6 is a similar sectional view taken on the line 6-6 of Fig. 1.

7 is a similar view to that shown in 'Fig. 1, illustrating my improved non-skid automobile wheel as it would appear when in use.

As here embodied my improved non-skid automobile wheel comprises a telly band 10, or rim of the usual ring shaped construction provided adapted to receive the tire 13 which is secured thereto in the usual well known manner, such as is common to solid tires.

The hub 14 is substantially of tubular construction, and is provided with an axial opening 17 adapted to rece ve the axle shaft of the automobile and is provided with any suitable means rigidly and removably securing the said hub to the axle shaiit, as is required by the design and type of the axle shaft, and which does not constitute a part of my invention.

The reinforcing hub 18 is of ring shaped construction somewhat larger in size or diameter than the hub 14 and is co-axially secured thereto by the spokes 19 radially positioned or extended from the said hub. The main spokes 20, preferably three in number, are provided with enlarged inner extremities 21, positioned intermediate the hub 14 and the reinforcing hub 17 and are secured to the two latter mentioned elements, and extended through apertures formed in the said reinforcing hub. The main spokes 20 are radiwith flanged elements 11 and 12,

ally disposed from tlie said hub 14, and are positioned or spaced at approximately 90 apart, and are secured at their extendedextremities to the telly band 10. The main spokes-20am provided with side extended elements 22, located in proximity to the extended extremities of the said main spokes and which extend outwardly heretrom. The extended elements 22 have formed therein serrations 23 or teeth, for the purpose hereinafter set forth.

Brackets 24 are secured to and extended inwardly from the telly band and are posi tioned intermediate the main spokes Similar brackets 25 and 26 are positioned or spaced at approximately 9O. apart, and are located equidistant from the two'ot the said main spokes which are oppositely extended. The brackets 24, 25 and 26 are provided with outwardly, side extended elements 27 having formed therein apertures adapted to freely receive the traction band 28. Similar apertures are formed in the extended elements 22 of the main spokes 20; The band 28 is of spring steel construction and is formed or bent substantially circular, and has its extremities 29 and 30, formed or bent inwardly, and secured as at 31 and 32, respectively, to the extended extremities of the supports 33 and 34, respectively. I The supports 33 and 34 are of spring steel construction, formed or bent are shaped and are secured as at and 36, at their inner extremities to the extended extremities 01" the brackets 37 and 38 secured to and radially extended from the reiniorc ing hub 18.

Tension spr1ngs39 and 40 are secured to l the extended extremities of thesupports 33 and 34, respectively, and are secured to the lug element 41 of the reinforcing hub 18,

positioned intermediatethe said supports 37 and 38.

A plurality of traction blocks 42 have formed therein apertures adapted to receive the band 28 and are secured thereto and are provided with serrations 43, located in the outer surface of the said blocks for the purpose as hereinafter set forth.

The above described construction is such as will permit the supports 33 and, 34, coacting with the springs 39 and 40 to normally'hold the traction band28 coaxial with the. e 13, and will permit any portion otthe said traction band to deflectso'mewhat in- 'wardly, as designated by the reterence'numeral 44-, When the traction block indicated v by the reference numeral 45 adjacent to the deflected portion of the said traction band encounters or engages ice, or any hard uneven road surface, as a means of provlding traction which Will obviously prevent skidding.

tension springs secured to a reinforcing hub.

2. In a non-skid automobile Wheel of the class described, a traction band engaging in apertures formed in brackets secured to and extended inwardly from the telly band of the said Wheel, and engaging in apertures formed in lugs extending laterally from the outer ends of the spokes, said traction band having a pluralityof traction blocks secured thereto, the extremities of the said band being secured to supports extended from a reintorcing hub co-axially mounted on the hub of the said Wheel, and tension springs secured to the said reinforcing hub and to the extended extremities of-the said supports.

In testimony whereof I have afiixed my signature.
